I have implemented Timer workalike that:

- when capturing, saves when it fires into the replay session
- when replaying, doesn't schedule itself, and instead is called by EventLoopInputDispatcher
- when neither capturing or replaying, it acts like a regular timer (by forwarding calls to an inner Timer instance).

The implementation in my branch supports the basic Timer API, but it should also support SuspendableTimer so that it can be used to make DOMTimer deterministic as well.
